First i like to give an overview on common IoT Protocols: #CoAP (Constrained Application Protocol -> Close to HTTP / REST ) #MQTT ( Message Queue Telemetry Transport -> Pub/Sub with Broker -> Well defined Quality of Service -> Newest addition Eclipse Amlem (formerly the core of IBM Watson IoT platform) -> Eclipse Sparkplug -> Standardization of the topics and payloads -> Interoperability!) , #DDS (Data Distribution Service -> Pub/Sub without Broker -> Drones / Robotics) #LwM2M (Lightweight M2M -> Runs on Top of CoAP or MQTT -> standard sets of payloads for sensors) #zenoh (https://zenoh.io/ Pub/Sub Protocol -> combines the advantages of #DDS and #MQTT) #eclipsefoundation #apache #opensource #lightweight (+ some comments that this is not complete and does not encompass Industrial and Building Automation) Then I would like to show the leading edge IoT protocol Zenoh. Saving Zenoh Payload to Apache IoTDB. After that I would like to dive into Panel and the awesome capabilities of Apache ECharts.

IoT Protocols
Connecting IoT devices – OSI Model
1. Physical (Bluetooth, Ethernet, LTE, NFC, RFID, Wi-Fi, Z-Wave, Zigbee)
2. Data link (IEEE 802.15.5, LPWAN)
3. Network (IP, 6LoWPAN)
4. Transport (Transmission Control Protocol (TCP), User Datagram Protocol (UDP))
5. Session

Zenoh
●
Zenoh unifies data in motion, data at rest and computations.
It elegantly blends traditional pub/sub with geo distributed storage,
queries and computations, while retaining a level of time and space
efficiency that is well beyond any of the mainstream stacks.
– Zero Overhead Pub/sub, Store/Query and Compute.
